VNH9030AQTR

VNH9030AQTR is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side driver and two low-side switches. The three dices are assembles in a QFN 6x6 triple pad 26+2L package equipped with three exposed islands for optimized dissipation performances. This package is specifically designed for the harsh automotive environment. The input signals INA and INB can directly interface the microcontroller to select the motor direction and the brake to VCC condition. Two selection pins (SEL0 and SEL1) to address the information are available on the multisense to the microcontroller. The multisense pin allows monitoring the motor current by delivering a current proportional to the motor current value and provides diagnostic feedback and case temperature according to the implemented truth table.
